[0028] Among them, the fixing mechanism includes a pneumatic cylinder 3, the pneumatic cylinder 3 is fixedly installed in the middle of the top of the audio 1, the front end of the pneumatic cylinder 3 is fixedly connected with a moving plate 4, the bottom of the moving plate 4 is fixedly connected with a limit block 5, the outer surface of the limit block 5 is movably connected with the inside of the chute 2, both sides of the top of the moving plate 4 are hinged with inclined rods 6, the other ends of the inclined rods 6 are hinged with clamping plates 7, the number of the clamping plates 7 is two, a dust mask 10 is movably connected to the inner sides of the two clamping plates 7, and the backs of the dust mask 10 and the clamping plates 7 are both movably connected with the front of the audio 1. The backward movement of the moving plate 4 will cause the two clamping plates 7 to move towards each other.

[0029] When the air cylinder 3 starts to operate, it will cause the moving plate 4 to drive the limit block 5 to move horizontally forward under the limiting action of the chute 2, and cause the inclined rod 6 to move, so that the two clamping plates 7 move horizontally away from each other, and finally the fixing effect on the dust mask 10 will be released.

[0030] Wherein, rectangular blocks 9 are fixedly connected to the top and bottom of the back surface of the clamping plate 7, and the outer surface of the rectangular block 9 is movably connected to the inside of the transverse groove 8.

[0031] When the inclined rod 6 moves, it will drive the clamping plate 7 and the transverse groove 8 to move horizontally left and right under the limiting action of the rectangular block 9.

[0032] Wherein, a rotating rod 11 is movably sleeved in the middle of the front surface of the dust mask 10, a handle 12 is fixedly connected to the front end of the rotating rod 11, a threaded rod 13 is threadedly sleeved inside the bottom of the handle 12, and a circular groove 14 is opened on the front surface of the dust mask 10 directly below the rotating rod 11.

[0033] When the handle 12 is rotated, the rotating rod 11 and the threaded rod 13 will rotate.

[0034] Wherein, a cam 15 is fixedly sleeved on the outer surface of the rotating rod 11, both sides of the outer surface of the cam 15 are movably connected to fixed blocks 16, the outside of the fixed block 16 is fixedly connected to a moving plate 17, and the back surfaces of the fixed block 16 and the moving plate 17 are both movably connected to the front surface of the dust mask 10.

[0035] When the cam 15 rotates, it will cause the two fixed blocks 16 to drive the two moving plates 17 to move horizontally away from each other.

[0036] Wherein, the number of the moving plates 17 is two, and a spring 19 is fixedly connected between the two moving plates 17.

[0037] Due to the design of the spring 19, the moving plate 17 has a good reset effect in subsequent movements.

[0038] Wherein, dust-proof plates 18 are movably connected to the front surface of the dust mask 10 above and below the rotating rod 11, rectangular grooves 20 are opened on both sides of the middle of the front surface of the dust mask 10, mounting blocks 21 are movably connected to the inside of the rectangular grooves 20, and the front surface of the mounting block 21 is fixedly connected to the back surface of the moving plate 17.

[0039] When the moving plate 17 moves, it will drive the mounting block 21 to move horizontally left and right under the limiting action of the rectangular groove 20.

[0040] Wherein, the number of the mounting blocks 21 is two, the sizes of the two mounting blocks 21 are the same, and the outer surfaces of the two mounting blocks 21 are smooth.

[0041] Such a design allows the installation block 21 to move more smoothly inside the rectangular groove 20 .

[0042] The working principle and use process of this utility model:

[0043] First, when the dust mask 10 needs to be disassembled and assembled, the pneumatic cylinder 3 is started, and the limit block 5 will drive the inclined rod 6 to move horizontally forward under the limiting action of the slide groove 2, and the two inclined rods 6 will move. At this time, under the limiting action of the transverse groove 8, the two clamping plates 7 will drive the transverse groove 8 to move horizontally away from each other, and finally the fixing effect of the dust mask 10 will be released, thereby achieving the purpose of quickly disassembling and assembling the dust mask 10, reducing the labor intensity of the operator, and improving the efficiency of disassembling and assembling the dust mask 10.

[0044] When the dustproof plate 18 is damaged and needs to be disassembled and replaced, the handle 12 is then rotated, which will cause the rotating rod 11 to drive the cam 15 to rotate, and the two fixed blocks 16 to drive the two movable plates 17 to move horizontally away from each other. At this time, under the limiting action of the rectangular groove 20, the two mounting blocks 21 will move horizontally away from each other, thereby releasing the fixing effect of the dustproof plate 18. At this time, rotating the threaded rod 13 to make it enter the inside of the circular groove 14 will achieve the fixing effect of the handle 12, completing the purpose of quickly replacing the dustproof plate 18 and reducing the labor intensity of the operator. Subsequently, the threaded rod 13 is rotated to make it disengage from the inside of the circular groove 14. At this time, the fixing effect on the handle 12 will be released. Subsequently, due to the elastic force of the spring 19, the two movable plates 17 will drive the mounting blocks 21 to move horizontally toward each other under the limiting action of the rectangular groove 20, and finally the fixing effect of the dustproof plate 18 will be restored.
